Camel-ZooKeeperRoutePolicy clarification - Slave Camel does not start after Master Camel shutdown

[Baltej Singh]

Second Attempt for feedback - Slave Camel does not start after Master Camel 
shutdown

Steps

1.  Start Master and Slave in separate cmds

2.  Master Camel server starts properly and prints message.

I was fired at Fri Nov 18 15:18:28 PST 2016

I was fired at Fri Nov 18 15:18:30 PST 2016

I was fired at Fri Nov 18 15:18:32 PST 2016

...

3.  Slave Camel server is started but not processing route, as expected.

4.  Kill Master - expect Slave to start route, but Slave route never starts

Subject: Camel-ZooKeeperRoutePolicy clarification - Slave Camel does not start 
after Master Camel shutdown

Hello,

I a simple application to test my first zookeeper/camel cluster.
When I Kill the Master Camel server, I expect Slave to start route, but Slave 
route never starts.
What is missing in the java code?

Thanks,
Baltej

Java code - Started with Camel in Action 2 sample quartz route

public class QuartzCronWithPolicy {

   public static void main(String args[]) throws Exception {

 CamelContext context = new DefaultCamelContext();
 ZooKeeperComponent zookeeperComponent = new ZooKeeperComponent();
 ZooKeeperConfiguration zooConfig = new ZooKeeperConfiguration();
zooConfig.addZookeeperServer("localhost:2182");
zooConfig.addZookeeperServer("localhost:2183");
zookeeperComponent.setConfiguration(zooConfig);

 context.addRoutes(new RouteBuilder() {
 public void configure() {
ZooKeeperRoutePolicy zooKeeperRoutePolicy = new 
ZooKeeperRoutePolicy("zookeeper://localhost:2181/ELECTION", 1);

from("quartz2://report?cron=0/2+*+*+*+*+?")
.routePolicy(zooKeeperRoutePolicy)
.setBody().simple("I was fired at ${header.fireTime}")
.to("stream:out")
.to("mock:end");
 }
 });

 context.start();
   }

Re: Simple IN with empty value in list

[Claus Ibsen]

Hi

Yeah that would work, but I just checked you can get empty value if
you use double comma, eg

',,gold,silver'

Re: Simple IN with empty value in list

[Karts]

In the end I just used .process() before the choice, got body.stringValue in
the Java code, tested and set an exchange header "isValid" to "true" if so,
and then subsequently tested for this in simple.

I didn't use something like .choice.when.simple("${body.stringValue.isEmpty}
|| ${body.stringValue} in 'gold,silver’")  as the simple block has multiple
&& and parentheses aren't supported yet for an || condition inside of there,
i.e. operator precedence.

using externalized xslt for transformation from server

[ravi21588]

Hi All,
Iam using camel 2.10 with Jboss EAP 6.1 server.
I would like to externalize XSLT for transformation by placing it as a file
in some location in server.
Can you please let me know how can i acheive.
The XSLT transformation frequently changes,will the xslt be picked correctly
without any restart?

Re: Simple IN with empty value in list

[Karts]

Sorry, to be clear, body.stringValue could be "", "gold", "silver", "bronze",
"platinum", etc.

I am trying to test so that only "", "gold" or "silver" are allowed before
moving forward, which is why I have the comma at the start, to allow for a
blank (not null) value:

.choice.when.simple("${body.stringValue} in ',gold,silver'")

But I'm finding if body.stringValue="", it does not satisfy the condition.
Is there another way I can do this?

Thanks

Camel Mail Component doesn't handle multiple attachments with same file name properly

[Petteri]

Hi,

I'm using Apache Camel and its mail component to read emails and their 
attachments.


I have encountered a problem which occurs when handling mails with 
multiple attachments using the same file name.


It seems that the problem is caused by the use of Map type in org.apache.camel.component.mail.MailBinding. 
Attachments are looped and checked against this map. If the map already 
contains a key with the same file name, attachment is skipped:


https://github.com/apache/camel/blob/camel-2.10.x/components/camel-mail/src/main/java/org/apache/camel/component/mail/MailBinding.java#L327

Maybe this key value could be somehow incremented so the map could 
contain all attachments despite of their file names?


I'm using Camel version 2.10.7 but the code seems to be unchanged by 
this part in current version too.


This kind of mails are regularly coming from end users of our software 
and there's no easy way to circumvent this from our side.


Thanks.

You have a comma before gold. It should just be 'gold,silver'
